Switching valve with slider

Abstract

Disclosed herein is a switching valve for transmitting of fluids. In particular, disclosed herein is a switching valve for filling of gas tanks having a housing with an inlet area and an outlet portion. A check valve, a vent valve, and an inlet valve can be disposed within the housing. The vent valve and the inlet valve can be controlled by a slide that is coupled with a pivoting lever which is actuated by a control valve in a pressure controlled manner.

1. A switching valve for transmitting of fluids comprising an inlet area and an outlet portion at a housing, in which a check valve, a vent valve and an inlet valve are disposed, wherein the vent valve and the inlet valve are controlled by a slide, wherein the slide is coupled with a pivoting lever, which is actuated by a control element in a pressure controlled manner. 
     
     
       2. The switching valve according to  claim 1 , wherein the control element is connected at the inlet area and at the outlet portion with a bypass line. 
     
     
       3. The switching valve according to  claim 1 , wherein the pivoting lever engages in an annular groove of the slide. 
     
     
       4. The switching valve according to  claim 1 , wherein the switching is for filling of gas tanks. 
     
     
       5. The switching valve according to  claim 1 , wherein the control element is a pressure responsive piston. 
     
     
       6. The switching valve according to  claim 1 , wherein the pivoting lever is asymmetrically arranged at a pivot axis in relation to its length. 
     
     
       7. The switching valve according to  claim 6 , wherein the pivoting lever has a lever length transmission of 3:1 or more. 
     
     
       8. The switching valve according to  claim 1 , wherein the pivoting lever is hinged at a piston of the control element. 
     
     
       9. The switching valve according to  claim 8 , wherein the piston is loaded by a spring. 
     
     
       10. The switching valve according to  claim 8 , wherein the piston has same piston cross-sections at the inlet side and the discharge side. 
     
     
       11. The switching valve according to  claim 8 , wherein the pivoting lever is hinged at the piston by a bolt. 
     
     
       12. The switching valve according to  claim 1 , wherein the control element is fitted onto the housing. 
     
     
       13. The switching valve according to  claim 12 , wherein the control element is fitted onto the housing at a middle housing part. 
     
     
       14. The switching valve according to  claim 12 , wherein the control element is fixed via screws at an intermediate housing. 
     
     
       15. The switching valve according to  claim 14 , wherein the intermediate housing also houses the pivot axis.
